Choose the cheaper item to be 1 u.
The toy car costs 4 times as much as the doll.
The doll is cheaper.
Cost of the toy car = 4 u = $40
Cost of the doll = 1 u
(a)
Cost of the doll
= 40 ÷ 4
= $10
(b)
Cost of the toy car more than the doll
= 4 u - 1 u
= 3 u
= 3 x 10
= $30
(c)
Cost of 1 toy car and 1 doll
= 4 u + 1 u
= 5 u
= 5 x 10
= $50
(d)
Cost of 7 toy cars and 5 dolls
= 7 x 4 u + 5 x 1 u
= 28 u + 5 u
= 33 u
= 33 x 10
= $330
Answer(s): (a) $10; (b) $30; (c) $50; (d) $330
